Connecting Measurement Devices
Example
The following example connection can be used to measure low resistance. The sense
line is extended to the probing pad, and contacts the force line through the pad, so
the voltage drop due to the residual resistance caused by cables and test leads is
canceled. To reduce the leakage current, use coaxial cables.
WARNING For safety, prepare and attach a shield cover to the connector plate to avoid
touching the joints on the wiring side of connectors. And ground the cover.
Wrap an insulator around the naked conductors of coaxial cable to avoid
touching it.
Pour des raisons de sécurité, préparez et fixez un couvercle protecteur à la
plaque de raccord pour éviter de toucher les joints du côté du câblage des
connecteurs. Et mettez le couvercle à la terre.
Enroulez un isolant autour des conducteurs dénudés du câble coaxial afin
d'éviter de les toucher.
WARNING To prevent electrical shock and DUT damage, do not connect or disconnect the
DUT while the instrument is applying voltage or current.
When you touch the DUT after measurement, devise a countermeasure of
residual charge and heat to prevent electrical shock and burn. Use glove and
any tool. Also have enough time for discharge and radiation.
Afin d’éviter toute décharge électrique et dommage MST, ne branchez ou
débranchez pas la sortie MST alors que l'appareil envoie de la tension ou du
courant.
